JTBC's Saturday-Sunday drama "The Efficient Romance of Single Men and Women" episode 10 saw the romance between Lee Ui-yeong (played by Han Ji-min) and Song Tae-seop (played by Park Sung-hoon) deepen, while an unexpected family variable emerged. Episode 10 recorded viewership ratings of 4.4% in the Seoul metropolitan area and 4.4% nationwide.

Previously, Lee Ui-yeong, who felt bewildered by a blind date disguised as a business meeting, received an apology from her team leader and was encouraged to take a leave of absence from work. During her leave, Lee Ui-yeong enjoyed a date at Song Tae-seop's woodworking studio and realized that the moments spent with him were the happiest.

While on leave, Lee Ui-yeong went on a business trip to Sokcho to help her junior, Jeong Hyeon-min. Upon hearing this, Song Tae-seop expressed his intention to join her after his schedule ended. This allowed the two to create new memories during their first overnight trip.

In Sokcho, Lee Ui-yeong and Song Tae-seop coincidentally met Jeong Hyeon-min and his girlfriend Lim Seung-jun, and enjoyed a double date. They also confirmed their feelings for each other during a Ferris wheel date. Afterward, the two further developed their relationship by sharing their first night together as a couple.

While checking out of the hotel, Lee Ui-yeong's father, Lee Tae-seong (played by Park Yoon-hee), appeared before Lee Ui-yeong and Song Tae-seop, complicating the situation. Lee Tae-seong was separated from Lee Ui-yeong's mother, Park Jeong-im.
